Dear FDDI experts,

We are planning to install 2 FDDI rings  and we are looking for comments
or experiences from users.

Here are some questions:

I have a host A connected to an ethernet segment. The ethernet segment is
connected on an FDDI bridge and the bridge on an FDDI ring. I have a
host B connected to an ethernet segment. The ethernet segment is connected
on a FDDI ethernet router and the router on the ring.

My question is: Will A talk to B?

The bridge will be Dec compatible translation bridge.

What can some one gain by having bridges mixed with routers?

If routers are as fast as bridges why will some one use bridges?

Do you have any experience with a router interfacing more than 2 ethernets
and an FDDI? Did you notice or measure any performance degradation.

I would like to have seperate measured filtering rates and forwarding rates
for bridges and routers.

Thank you for any pointers, I will summarize if I get any response.
